The avocados were irradiated on the day of arrival or held d under refrigeration or at ambient temperature. The doses absorbed were between Gy. Daily observations were made on external appearance, and when ripe the avocados were opened for internal examination. Abstract by Guy Hallman. Irradiation of Mangoes.https://buibasopho.ga

Radiation Effects on Skin-coated Alphonso Mangoes. DOI: The respiratory patterns of skin-coated and uncoated Alphonso mangoes, either unirradiated or irradiated under gaseous atmospheres like air, nitrogen, or carbon dioxide, were studied. The skins were coated with an emulsion made of an acetylated monoglyceride preparation.
Skin-coated fruits show physiological damage presumably due to too much inhibition of respiration. This defect is rectified by a spurt in respiratory activity when fruits are irradiated in air or nitrogen. Irradiation in carbon dioxide, which also retards respiration, shows physiological damage which is reversible, the recovery of organoleptic qualities being possible to some extent. Suppression of respiration beyond an optimum level seems to be responsible for irreversible damage to the fruit.
Organoleptic evaluation, analysis for fruit constituents, skin color, and pressure tests showed that storage life of the fruit can be increased by combining skin-coating with irradiation under either air or nitrogen. Irradiation of mangoes I Radiation-induced delay in ripening of Alphonso mangoes. Journal of Food Science 31 6 : Extension of storage life of unripe and mature Alphonse mangoes could he achieved at an optimum dose of 25 krads when irradiated under air, nitrogen, or carbon dioxide.
Nitrogen atmosphere during irradiation is of some advantage in minimizing changes in organoleptic quality, ascorbic acid, and carotenoids, and at the same time allowing the least spoilage of fruit. Judging from skin color and fruit firmness, a six-day delay in ripening could be expected in fruits irradiated with 25 krads under nitrogen or air. Radiation effect on fruit skin is more prominent in terms of inhibition in chlorophyll disappearance and earotenoid formation than in ripening changes in the meat of the fruit.
Dharkar, S. Effect of gamma irradiation on ripening and quality of nectarines and peaches. Gamma irradiation with doses of kilorad Krad initiated the climacteric and ripening sequence in nectarines and peaches Prunus persica , apparently by inducing the unripe fruits to produce stimulatory amounts of ethylene C2H4. Rates of CO2 and C2H4 production were much higher in irradiated than in unirradiated fruits at every stage of the climacteric sequence, and irradiated fruits ripened days earlier. Irradiated fruits were noticeably redder than unirradiated ones.
The skin and flesh of irradiated Elberta' and "Suncrest number 72" peaches contained more anthocyanin than unirradiated fruits. Irradiated nectarines were acceptable for flavor and appearance, but aroma and texture were poor. Loss of flesh firmness in irradiated fruits made them so susceptible to mechanical injury that irradiation as a protective technology for these fruits may be precluded.
Maxie, E. The influence of gamma radiation on textural changes in peaches. Peaches of the Maygold, Southland, Loring and Dixi-land varieties were used to measure textural changes resulting from gamma radiation. The Maygold peaches were irradiated at levels of 0, , and krads and then stored at 67 degrees F. Irradiation induced softening of the fruit; however, the rate of softening was greatest for peaches measured after 1 day's storage.
Effects of gamma radiation on bananas. Anthracnose spoilage in bananas inoculated with spores of Gloeosporium musarum was markedly retarded by gamma radiation doses of Krad or higher.
Organoleptical-ly bananas irradiated in a well ventilated chamber compared favorably with control fruit. Color, flavor and texture developed fully, though more slowly with increasing doses. Bananas irradiated in small closed chambers showed extensive skin-splitting and discoloration and in some instances failed to ripen fully. This is attributed to ozone rather than to radiation damage. No visible damage to fruit was noted from radiation per se.
Stored irradiated Navel oranges became lighter in color than control fruit, as evidenced by reflectance measurements and color specifica tions. This difference was greater after 30 days at 50 F than at 35 and 68 F. Initially light- and dark-colored Temples exhibited increasing reflectance values during storage. Differences in per cent reflectance due to irradiation were most pronounced in the light-colored fruit stored at 50 F.
The stored irradiated Temples possessed a yellow-orange color as compared to the orange color of the non-irradiated fruit. Flavedo carotenoids were extracted and sep arated by thin-layer chromatography. Radiation- induced color loss was due to decreased concen trations of a relatively few carotenoids. The chief losses of Temple carotenoids were in an esterified orange-colored xanthophyll and an un- esterified yellow xanthophyll.

Postharvest quality of G. A- treated Florida grapefruit after gamma irradiation with TBZ and storage. Irradiation of Duncan grapefruit, Pineapple and Valencia oranges and Temples. The citrus fruits examined showed irradiation induced peel injury. The severity of peel injury was greater as the radiation doses increased or the storage temperature and duration increased. There were no differences in the organoleptic quality attributes of irradiated grapefruit stored 19 and 20 days at 65 and 58 F, respectively.
In view of the severity of peel injury irradiation cannot be recommended for preservation of Florida citrus fruits.
